3.2.2 When there is wall (or similar obstruction) above the unit, keep the distance between
the unit top and the wall at least 3000mm or above. When the unit is located in an open
space with no obstruction from front, back, left and right, keep the distance between the
unit top and wall at least 1500mm or above (See Fig.7). When the distance is limited within
1500mm or the unit is not set in an open space, air return pipe is required to be installed in
order to keep good ventilation (See Fig.8).
